A total of 33 renal venograms were reviewed to determine the incidence of radiographically demonstrable valves. Valves were identified in five of 22 left renal venograms and two of 11 right renal venograms. On the right side in both patients the valve was located at the junction of the renal vein with the inferior vena cava. On the left, valves were located in the main renal vein proximal or distal to the gonadal vein and in one patient in a segmental upper pole tributary. These valves are significant because of the technical difficulties they can create during renal venography and their possible usefulness in selecting the site of anastomosis in patients undergoing distal splenorenal shunts.
共回顾了33份肾静脉造影，以确定影像学可显示瓣膜的发生率。在22份左肾静脉造影中有5份发现瓣膜，在11份右肾静脉造影中有2份发现瓣膜。右侧的两位患者中，瓣膜均位于肾静脉与下腔静脉的交界处。左侧，瓣膜位于性腺静脉近端或远端的肾主静脉内，还有一位患者的瓣膜位于上段肾极分支。这些瓣膜很重要，因为它们会在肾静脉造影时造成技术困难，且在选择远端脾肾分流术患者的吻合部位时可能有用。
